BWOs are bringing action from fish in the Last Chance-Harriman area and a few mahogany duns are around. Terrestrial insects and caddisflies are on the decline. Stonefly nymph patterns seem to work well in Box Canyon, especially during overcast and low light conditions. Browns are moving on the lower river meaning it is time to break out streamer patterns to be presented under low light conditions.Just above Ashton reservoir is a good place to try, but so are below Ashton Dam and Chester Dam. The uncertain weather predicted for the next several days also means good BWO activity, so don’t choose between their life cycle patterns and streamers. Take both!
